Hi,

The ispc compiler get error when I try to delete a soa pointer. I'm using ispc 1.9.1 (llvm 3.8) on Mac OS 10.12.3 . 

Compiler said: 

Assertion failed: (castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"), function BitCastInst, file /Volumes/bpartb/_users/dybaboki/llvm/llvm-3.8/lib/IR/Instructions.cpp, line 3261.

main.cpp(235): FATAL ERROR: Unhandled signal sent to process; terminating.

Here's the sample code. If I omit the last line, build will succeed. Also, looks like some soa test cases in ispc repo never delete after new (e.g. ispc/tests/soa-21.ispc). 

Did I miss something? Thanks in advance

struct vec3f 
{
  float x;
  float y;
  float z;
};

soa<8> vec3f * uniform color = uniform new soa<8> vec3f[1000];
delete color;
